ISX cam grinds

[ynot]

I've been wondering this same sort of stuff for awhile now, if you go by part numbers the valve cam is the same on all the motors. The injector cam part # changes between the three tiers which would lead me to believe theres something different between them. Same for injectors they have a different part number for each of the three tiers as well and browsing around Cal's seeing the injection durations change adds to my belief that there's 3 sizes of injectors too.

Ive been meaning to do some reading on cam measurements and stop by the local junk yard an measure and compare them.

In all my searching I've never found anyone that's publish or ever talked about flow testing the CACs and turbos on our trucks as is. But if you go too pickup truck forums you might be able to find some turbo flow info your looking for, those guys are way more intp part specs then the big truck world is
